Many people think that indoor and outdoor stage sound equipment and systems can be used the same, but in fact, due to the difference in venues, the stage sound used will often be different. So we cannot use the same scheme to configure different stage sound, today JAZZLONG sound manufacturers will come and talk to you about some requirements for outdoor stage sound;
1. The sound system must have a strong power reserve: The outdoor open-air sound field needs powerful sound, because the outdoor sound field needs to increase the sound pressure level by 3db, the power needs to be increased by 10 times. According to the formula 10logp2/p1=xdb, the specific numerical value of the sound field can be calculated.
2. Speaker placement at a high position: The speaker placement of outdoor stage performances cannot be too low. Low-positioned speakers emit sound waves that are easily absorbed by the audience's body, causing the scattering absorption phenomenon, especially for the loss of mid-high frequencies. Therefore, the speakers should be placed high, with the use of medium or high-frequency horns and outdoor-specific speakers (speakers with high-power high-frequency horns inside), so that the sound waves emitted by the speakers can radiate farther in the air, allowing the audience area to receive sufficient sound pressure level.
